USER MANUAL Bonitron M3452 Heavy Duty Braking Transistors are used with AC drives to allow full power braking and eliminate overvoltage faults. This permits controlled braking and dramatically shortens motor stopping time. The M3452 works with Variable Frequency Drives (with DC bus connections) to monitor the DC bus. If overvoltage occurs, the M3452 shunts the excess energy through an external braking resistor to prevent overvoltage faults. The need for regenerated voltage control occurs in applications where the frequency of an AC motor at times exceeds that of its variable frequency drive. In this case, the motor acts as a generator. The energy generated by the motor must be dissipated as heat or returned to the power line. If this energy is not controlled, the motor may run with high peak voltages, the energy may be dissipated as heat in the motor, or the drive may trip on an over-voltage condition. The R7 option allows for Master/Slave operation to be changed on the fly in multiple module systems to allow for fault redundancy in the control sections for critical applications. The R7E option includes all the functions of the R7 option, while adding extended status I/O as well as the Bus Discharge feature. This can be used to drain a capacitor bank for quicker servicing at power down. This can be an issue with drive systems that have large capacitor banks or use oversized capacitor banks for power dip immunity. Under normal circumstances, these banks can take excessive amounts of time to reach safe working levels. The Bus Discharge feature allows the braking system to be used as the bleeder resistor, and brings the bus voltage down much quicker. Discounted if you buy all!!
